靖安油田为长庆油田采油三厂的主力油田之一。以前主要使用CQ—C3破乳剂,由于该破乳剂是1992年针对红井子及油房庄油田的原油物性而研制的。对于靖安原油,该产品已不能有效地破除溢流沉降罐的中间层,导致脱水温度偏高,脱水速度慢,已不能满足快速脱水的要求。针对上述问题研制出 Jing’an Oilfield is one of the major oilfields of the Third Oil Production Plant in Changqing Oilfield. In the past, the CQ-C3 demulsifier was mainly used because the demulsifier was developed in 1992 against the crude oil properties of the Hongjingzi and Youfangzhuang oil fields. For Jing’an crude oil, the product can not effectively remove the middle layer of overflow settling tank, leading to high dehydration temperature and slow dehydration, which can not meet the requirements of rapid dehydration. Developed for the above problems
